The first number is a , the second number is b , the third number is c

( 0 < a < b < c )

The sum of three numbers is 182

⇒ a + b + c = 182 (1)

The second is 6 times bigger than the first

⇒ b = 6a (2)

The third is 14 times bigger than the second number

⇒ c = 14b = 14.6a = 84a (3)

(1),(2),(3): ⇒ a + 6a + 84a = 182

⇒ 91a = 182

⇒ a = 2

⇒ b = 6a = 6.2 = 12

⇒ c = 14b = 14.12 = 168

Those numbers are 2 , 12 , 168

ok done. Thank to me :>

Answer:

The numbers are
2,12,168

Explanation:

Let the numbers be
a,b,c

We have

The sum of three numbers is
182


a+b+c=182-----eqn1

The second is
6 times bigger than the first


b=6a-----eqn2

The third is
14 times bigger than the second number


c=14b-------eqn3

Substituting in eqn 3


c=14* 6a=84a ----eqn4

Substituting in eqn 1


a+6a+84a=182\\\\91a=182\\\\a=2

Substituting in eqn 2


b=6*2=12

Substituting in eqn 3


c=14*12=168

The numbers are
2,12,168
